BACKGROUND OF THE INVENTION

N-Aryl amines and amides are important substructures in natural productsand industrial chemicals, such as pharmaceuticals, dyes, andagricultural products. Palladium-catalyzed methods for the N-arylationof amines and amides are now widely-exploited for the synthesis ofarylamine and N-arylamide moieties in pharmaceuticals, materials withimportant electronic properties, and ligands for early metal catalysts.Likewise, the palladium-catalyzed coupling to form carbon-carbon bondsbetween an aryl or vinyl halide and a carbon nucleophile is widely used.See, e.g., Stille, J. K. Angew. Chem., Int. Ed. Engl., 25:508–524(1986); Miyaura, N. et al., Chem. Rev., 95:2457–2483 (1995); Negishi, E.Acc. Chem. Res., 15:340–348 (1982).

However, the ever-increasing cost of palladium detracts from the allureof these powerful methods. Consequently, a need exists for a general andefficient catalytic method for synthesizing N-aryl amines and amides,from aryl halides and the corresponding amines and amides, based on acatalyst that does not comprise a rare, costly transition metal, such aspalladium. Likewise, a need also exists for a general and efficientcatalytic method for forming carbon-carbon bonds between an aryl orvinyl halide and a carbon nucleophile, based on a catalyst that does notcomprise a rare, costly transition metal, such as palladium.

In 1998, bulk palladium sold on the international metal market forroughly five-thousand-times the cost of bulk copper. Therefore, based oncatalyst cost, the aforementioned transformations would be orders ofmagnitude more appealing if they could be achieved with catalystscomprising copper in place of palladium.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to copper-catalyzed carbon-heteroatom andcarbon-carbon bond-forming methods. In certain embodiments, the presentinvention relates to copper-catalyzed methods of forming acarbon-nitrogen bond between the nitrogen atom of an amide or aminemoiety and the activated carbon of an aryl, heteroaryl, or vinyl halideor sulfonate. In additional embodiments, the present invention relatesto copper-catalyzed methods of forming a carbon-nitrogen bond between anitrogen atom of an acyl hydrazine and the activated carbon of an aryl,heteroaryl, or vinyl halide or sulfonate.

The present invention also relates to copper-catalyzedmethods of forming a carbon-carbon bond between a reactant comprising anucleophilic carbon atom, e.g., an enolate or malonate anion, and theactivated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate.Importantly, all the methods of the present invention are relativelyinexpensive to practice due to the low cost of the copper comprised bythe catalysts.

Cu-Catalyzed N-Arylation of Amides

The coupling of aryl iodides and bromides with amides, the so-calledGoldberg reaction, is not very general in terms of substrate scope,often requiring stoichiometric quantities of copper complexes. Moreover,as with the related Ullmann reaction, the reaction conditions for theGoldberg reaction are often quite harsh, with required temperatures ashigh as 210° C. Nevertheless, the methods of the present inventioneffect these reactions using only 1 mol % CuI and have successfully usedas little as 0.2 mol % CuI. In many instances, a system derived from 1%CuI, 10% (racemic)-trans-cyclohexane-1,2-diamine, and K₃PO₄ or Cs₂CO₃provides an outstanding catalyst for the amidation of aryl iodides.Importantly, CuI is an air-stable Cu(I) source. As can been seen in theExemplification, the process enjoys broad substrate scope with respectto the aryl iodide component. Notably, the arylation of a 2°amide-containing substrate and of 4-iodoaniline are possible;Pd-catalyzed C—N bond-forming processes with substrates that containthese functional groups are not successful. We have also been able toN-arylate N-BOC hydrazine. Further, this process provides a conveniententry into the synthesis of hydrazines, and, therefore, a means toaccess Fischer indole substrates and other heterocycle synthons.

The copper-catalyzed methods of the present invention allow theamidation of aryl bromides. These reactions typically use 1–20 mol %CuI; for example, in one embodiment, 1 mol % CuI was used, yielding theproduct in 90% yield. Additionally, the coupling of an unactivated arylchloride with an amide has also been achieved using the methods of thepresent invention.

The methods of the present invention also work well for the coupling ofaryl iodides with primary amides; in fact, there appear to be nolimitations on the nature of the acyl substituent (R in RC(O)NH₂). Withrespect to 2° amides, N-acyl anilines and lactams are preferredsubstrates. N-formyl amides derived from alkyl amines are satisfactorysubstrates. Consequently, we believe that steric hindrance influencesthe outcome of the methods. In embodiments wherein ligand arylationcompetes with substrate arylation, the use of a 1,10-phenanthroline oran N,N′-dimethyl-1,2-diamine gives improved results.

In preferred embodiments, the pK_(a) of the amide is in the particularrange of 20–25, as measured in DMSO. Generally, strong bases are lesseffective than weak bases in the methods of the present invention; forexample, Cs₂CO₃ and K₃PO₄ are efficient bases in many embodiments. Forthe coupling of aryl bromides at low catalyst loadings, and for thecoupling of aryl chlorides, the use of K₂CO₃ is preferred. These resultsare consistent with the notion that it is important to keep theconcentration of the deprotonated amide low in order to preventdeactivation of the catalyst. Interestingly, to a certain extent,decreasing the catalyst loading does not appear to compromise thereaction efficiency.

Cu-Catalyzed N-Arylation of Heterocycles

In terms of the desirability of the products, some of the most importantsubstrates for the catalyzed N-arylation are nitrogen-containingheterocycles, e.g., pyrrole, and indole. Previous reports ofcopper-mediated heterocycle N-arylations suffer from limitations similarto those of the Ullmann reaction. Likewise, the Cu-promoted or catalyzedcoupling of heterocycles with aryl boronic acids is of limited scope.Moreover, boronic acids are much less attractive as precursors than arylhalides. Accordingly, a general solution to the arylation ofheterocycles has been sought for years.

The methods of the present invention allow N-arylation ofnitrogen-containing heteroaromatics using 2-haloanisole or 2-methylindole as one of the coupling partners; in these embodiments, themethods of the present invention afford the desired products nearlyquantitatively, whereas the same transformations are very difficultusing Pd catalysts. Further, the methods of the present invention enableN-arylation of pyrazole and indazole. Accordingly, the methods of thepresent invention enable the arylation of a variety of nitrogenheterocycles.

Mild, inexpensive bases, such as K₃PO₄ and K₂CO₃, are effective in thesetransformations. These reactions are usually very clean, and arenereduction is typically less problematic than in corresponding Pdsystems. The methods of the present invention are often able to effectthe desired coupling with as little as 1 mol % CuI; however, elevatedtemperatures, e.g., 110° C., are normally required for the reaction.Nevertheless, in certain embodiments, a method of the present inventionprovides an N-aryl heteroaromatic in good yield when performed at roomtemperature.

For convenience, certain terms employed in the specification, examples,and appended claims are collected here.

The term “nucleophile” is recognized in the art, and as used hereinmeans a chemical moiety having a reactive pair of electrons. Examples ofnucleophiles include uncharged compounds such as water, amines,mercaptans and alcohols, and charged moieties such as alkoxides,thiolates, carbanions, and a variety of organic and inorganic anions.Illustrative anionic nucleophiles include simple anions such ashydroxide, azide, cyanide, thiocyanate, acetate, formate orchloroformate, and bisulfite. Organometallic reagents such asorganocuprates, organozincs, organolithiums, Grignard reagents,enolates, acetylides, and the like may, under appropriate reactionconditions, be suitable nucleophiles. Hydride may also be a suitablenucleophile when reduction of the substrate is desired.

The term “electrophile” is art-recognized and refers to chemicalmoieties which can accept a pair of electrons from a nucleophile asdefined above. Electrophiles useful in the method of the presentinvention include cyclic compounds such as epoxides, aziridines,episulfides, cyclic sulfates, carbonates, lactones, lactams and thelike. Non-cyclic electrophiles include sulfates, sulfonates (e.g.tosylates), chlorides, bromides, iodides, and the like.

The terms “electrophilic atom”, “electrophilic center” and “reactivecenter” as used herein refer to the atom of the substrate which isattacked by, and forms a new bond to, the nucleophile. In most (but notall) cases, this will also be the atom from which the leaving groupdeparts.

The term “electron-withdrawing group” is recognized in the art and asused herein means a functionality which draws electrons to itself morethan a hydrogen atom would at the same position. Exemplaryelectron-withdrawing groups include nitro, ketone, aldehyde, sulfonyl,trifluoromethyl, —CN, chloride, and the like. The term“electron-donating group”, as used herein, means a functionality whichdraws electrons to itself less than a hydrogen atom would at the sameposition. Exemplary electron-donating groups include amino, methoxy, andthe like.

The terms “Lewis base” and “Lewis basic” are recognized in the art, andrefer to a chemical moiety capable of donating a pair of electrons undercertain reaction conditions. Examples of Lewis basic moieties includeuncharged compounds such as alcohols, thiols, olefins, and amines, andcharged moieties such as alkoxides, thiolates, carbanions, and a varietyof other organic anions.

The term “Bronsted base” is art-recognized and refers to an uncharged orcharged atom or molecule, e.g., an oxide, amine, alkoxide, or carbonate,that is a proton acceptor.

The terms “Lewis acid” and “Lewis acidic” are art-recognized and referto chemical moieties which can accept a pair of electrons from a Lewisbase.

The term “meso compound” is recognized in the art and means a chemicalcompound which has at least two chiral centers but is achiral due to aninternal plane, or point, of symmetry.

The term “chiral” refers to molecules which have the property ofnon-superimposability on their mirror image partner, while the term“achiral” refers to molecules which are superimposable on their mirrorimage partner. A “prochiral molecule” is an achiral molecule which hasthe potential to be converted to a chiral molecule in a particularprocess.

The term “stereoisomers” refers to compounds which have identicalchemical constitution, but differ with regard to the arrangement oftheir atoms or groups in space. In particular, the term “enantiomers”refers to two stereoisomers of a compound which are non-superimposablemirror images of one another. The term “diastereomers”, on the otherhand, refers to the relationship between a pair of stereoisomers thatcomprise two or more asymmetric centers and are not mirror images of oneanother.

Furthermore, a “stereoselective process” is one which produces aparticular stereoisomer of a reaction product in preference to otherpossible stereoisomers of that product. An “enantioselective process” isone which favors production of one of the two possible enantiomers of areaction product. The subject method is said to produce a“stereoselectively-enriched” product (e.g., enantioselectively-enrichedor diastereoselectively-enriched) when the yield of a particularstereoisomer of the product is greater by a statistically significantamount relative to the yield of that stereoisomer resulting from thesame reaction run in the absence of a chiral catalyst. For example, anenantioselective reaction catalyzed by one of the subject chiralcatalysts will yield an e.e. for a particular enantiomer that is largerthan the e.e. of the reaction lacking the chiral catalyst.

The term “regioisomers” refers to compounds which have the samemolecular formula but differ in the connectivity of the atoms.Accordingly, a “regioselective process” is one which favors theproduction of a particular regioisomer over others, e.g., the reactionproduces a statistically significant preponderence of a certainregioisomer.

The term “reaction product” means a compound which results from thereaction of a nucleophile and a substrate. In general, the term“reaction product” will be used herein to refer to a stable, isolablecompound, and not to unstable intermediates or transition states.

The term “substrate” is intended to mean a chemical compound which canreact with a nucleophile, or with a ring-expansion reagent, according tothe present invention, to yield at least one product having astereogenic center.

The term “catalytic amount” is recognized in the art and means asubstoichiometric amount relative to a reactant.

As discussed more fully below, the reactions contemplated in the presentinvention include reactions which are enantioselective,diastereoselective, and/or regioselective. An enantioselective reactionis a reaction which converts an achiral reactant to a chiral productenriched in one enantiomer. Enantioselectivity is generally quantifiedas “enantiomeric excess” (ee) defined as follows:% Enantiomeric Excess A(ee)=(% Enantiomer A)−(% Enantiomer B)where A and B are the enantiomers formed. Additional terms that are usedin conjunction with enatioselectivity include “optical purity” or“optical activity”. An enantioselective reaction yields a product withan e.e. greater than zero. Preferred enantioselective reactions yield aproduct with an e.e. greater than 20%, more preferably greater than 50%,even more preferably greater than 70%, and most preferably greater than80%.

A diastereoselective reaction converts a chiral reactant (which may beracemic or enantiomerically pure) to a product enriched in onediastereomer. If the chiral reactant is racemic, in the presence of achiral non-racemic reagent or catalyst, one reactant enantiomer mayreact more slowly than the other. This class of reaction is termed akinetic resolution, wherein the reactant enantiomers are resolved bydifferential reaction rate to yield both enantiomerically-enrichedproduct and enantimerically-enriched unreacted substrate. Kineticresolution is usually achieved by the use of sufficient reagent to reactwith only one reactant enantiomer (i.e. one-half mole of reagent permole of racemic substrate). Examples of catalytic reactions which havebeen used for kinetic resolution of racemic reactants include theSharpless epoxidation and the Noyori hydrogenation.

A regioselective reaction is a reaction which occurs preferentially atone reactive center rather than another non-identical reactive center.For example, a regioselective reaction of an unsymmetrically substitutedepoxide substrate would involve preferential reaction at one of the twoepoxide ring carbons.

The term “non-racemic” with respect to the chiral catalyst, means apreparation of catalyst having greater than 50% of a given enantiomer,more preferably at least 75%. “Substantially non-racemic” refers topreparations of the catalyst which have greater than 90% ee for a givenenantiomer of the catalyst, more preferably greater than 95% ee.

The term “alkyl” refers to the radical of saturated aliphatic groups,including straight-chain alkyl groups, branched-chain alkyl groups,cycloalkyl (alicyclic) groups, alkyl substituted cycloalkyl groups, andcycloalkyl substituted alkyl groups. In preferred embodiments, astraight chain or branched chain alkyl has 30 or fewer carbon atoms inits backbone (e.g., C₁–C₃₀ for straight chain, C₃–C₃₀ for branchedchain), and more preferably 20 of fewer. Likewise, preferred cycloalkylshave from 4–10 carbon atoms in their ring structure, and more preferablyhave 5, 6 or 7 carbons in the ring structure.

Additionally, with respect to asymmetricchelating ligands, the ligand may be provided as a single enantiomer, amixture of stereoisomers, or a racemic mixture. In certain embodiments,the ligand serves as the solvent for a method of the present invention.For example, in an embodiment wherein the ligand comprised by thecatalyst is an amine that is a liquid under the conditions forpracticing a method of the present invention, the method may bepracticed using said amine as the solvent.

The copper atom or ion and the ligand of the catalyst of the methods ofthe present invention may be added to the reaction mixture separately orsimultaneously, or they may be added in the form of preformed catalystcomplex. Although the methods of the present invention do not requirethe formation of a copper-chelating ligand complex, such complexes arelikely present. Moreover, the identity of the ligand effects variouscharacteristics of the methods of the present invention.

In certain embodiments, the catalyst of a method of the presentinvention is covalently tethered to a solid support, e.g., a polymerbead or a resin. For example, the ligand of a catalyst of the presentinvention may be covalently tethered to a solid support, e.g., a Wangresin. Additionally, one or more of the substrates of a method of thepresent invention may be covalently tethered to a solid support, e.g., apolymer bead or a resin. For example, the Z-X substrate of a method ofthe present invention may be covalently tethered to a solid support,e.g., a Wang resin. Alternatively, the nucleophilic substrate, i.e., thesubstrate that effectively replaces X in Z-X, of a method of the presentinvention may be covalently tethered to a solid support, e.g., a Wangresin. Further, in certain embodiments, both substrates may becovalently tethered to a solid support. In certain embodiments, one ormore of the substrates or the catalyst or any of them are isolated in asemi-permeable membrane, e.g., a dialysis bag.

Suitable Bases

A wide range of Bronsted bases may be used in the methods of the presentinvention. Generally, any Bronsted base may be used in the methods ofthe present invention. For example, suitable bases include K₃PO₄, K₂CO₃,Na₂CO₃, Tl₂CO₃, Cs₂CO₃, K(OtBu), Li(OtBu), Na(OtBu), K(OPh), andNa(OPh), or mixtures thereof. In certain embodiments, the Bronsted baseused will be selected from the group consisting of phosphates,carbonates, and alkoxides. In certain embodiments, the base is selectedfrom the group consisting of potassium phosphate, potassium carbonate,cesium carbonate, and sodium tert-butoxide.

Typically, there is no need to use large excesses of base in the methodsof the present invention. In certain embodiments, no more than fourequivalents of base are used, relative to the nucleophilic reactant. Inother embodiments, no more than two equivalents of base are used,relative to the nucleophilic reactant. Further, in reactions using thecorresponding anion of the nucleophilic reactant in place of itsconjugate base, there may be no need for additional base.

Nucleophiles

Nucleophiles which are useful in the methods of the present inventionmay be selected by the skilled artisan according to several criteria. Ingeneral, a suitable nucleophile will have one or more of the followingproperties: 1) It will be capable of reaction with the substrate at thedesired electrophilic site; 2) It will yield a useful product uponreaction with the substrate; 3) It will not react with the substrate atfunctionalities other than the desired electrophilic site; 4) It willreact with the substrate at least partly through a mechanism catalyzedby the chiral catalyst; 5) It will not substantially undergo furtherundesired reaction after reacting with the substrate in the desiredsense; and 6) It will not substantially react with or degrade thecatalyst. It will be understood that while undesirable side reactions(such as catalyst degradation) may occur, the rates of such reactionscan be rendered slow—through the selection of reactants andconditions—in comparison with the rate of the desired reaction(s).

Routine experimentation may be necessary to determine the preferrednucleophile for a given transformation. For example, if anitrogen-containing nucleophile is desired, in order to form acarbon-nitrogen bond, it may be selected from the group comprisingamines, amides, and imides. Further, heteroaromatics may also be used asthe nucleophilic reactant. For example, a carbon-nitrogen bond may beformed comprising the nitrogen of an optionally substituted indole,pyrrole, or carbazole. Moreover, numerous other nitrogen-containingfunctional groups serve as substrates in the instant methods of formingcarbon-nitrogen bonds. For example, hydrazines, acylhydrazines,hydrazones, imines, and alkoxycarbonylhydrazines are suitable substratesfor the carbon-nitrogen bond-forming methods of the present invention.

Similarly, an oxygen-containing nucleophile, such as an alcohol,alkoxide, or siloxane, may be used to form an oxygen-carbon bond; and asulfur-containing nucleophile, such as a mercaptan, may be used to forma carbon-sulfur bond. Likewise, a carbon nucleophile, e.g., a malonateor a beta-keto ester, may be used to form a carbon-carbon bond.Additional suitable nucleophiles will be apparent to those of ordinaryskill in the art of organic chemistry. A nucleophile introduced in thereaction mixture as an anion may comprise a conventional counterion,e.g., an alkali metal cation, alkaline earth cation, or ammonium ion. Incertain embodiments, the nucleophilic moiety may be part of thesubstrate, resulting in an intramolecular bond-forming reaction.

In certain embodiments, the nucleophile is selected from the groupconsisting of primary amides, secondary amides, lactams, hydrazines,imines, hydrazones, carbazates, primary amines, secondary amines,NH-containing heteroaromatics (e.g., pyrroles, indoles, and imidazoles),malonates, carbamates, imides, and alcohols.

The methods of the present invention may be used to form a bond betweenthe halogen-bearing or sulfonate-bearing carbon atom of an aryl halideor sulfonate, heteroaryl halide or sulfonate, or vinyl halide orsulfonate, and a nucleophilic nitrogen or carbon or oxygen atom of asecond molecule. Of course, as mentioned supra, the halogen-bearingcarbon of the aryl halide, heteroaryl halide, or vinyl halide, or thesulfonate-bearing carbon of the aryl sulfonate, heteroaryl sulfonate, orvinyl sulfonate, and the nucleophilic nitrogen or carbon may be part ofa single molecule, rendering the bond-formation intramolecular.

In certain embodiments, an aryl halide or sulfonate is used, wherein itsaryl moiety is a radical of an aromatic hydrocarbon (single orpolycylic), such as benzene, naphthalene, anthracene and phenanthrene.In certain embodiments, the aryl halide may be selected from the groupconsisting of optionally-substituted phenyl halides.

In certain embodiments, a heteroaryl halide or sulfonate is used,wherein its heteroaryl moiety is a radical of an heteroaromatic (singleor polycylic), such as pyrrole, thiophene, thianthrene, furan, pyran,isobenzofuran, chromene, xanthene, phenoxathiin, pyrrole, imidazole,pyrazole, thiazole, isothiazole, isoxazole, pyridine, pyrazine,pyrimidine, pyridazine, indolizine, isoindole, indole, indazole, purine,quinolizine, isoquinoline, quinoline, phthalazine, naphthyridine,quinoxaline, quinazoline, cinnoline, pteridine, carbazole, carboline,phenanthridine, acridine, perimidine, phenanthroline, phenazine,phenarsazine, phenothiazine, furazan, phenoxazine, pyrrolidine, oxolane,thiolane, oxazole, piperidine, piperazine, morpholine.

In general, suitable aromatic compounds have the formula Z_(p)ArX,wherein Ar is aryl or heteroaryl; and X is a sulfonate or a halogenselected from the group consisting of chlorine, bromine, and iodine. Incertain embodiments, X is a halide selected from the group consisting ofchlorine, bromine, and iodine. In certain embodiments, X represents asulfonate moiety. Further, Z represents one or more optionalsubstituents on the aromatic ring, though each occurence of Z (p>1) isindependently selected. By way of example only, each incidence ofsubstitution independently can be, as valence and stability permit, ahalogen, a lower alkyl, a lower alkenyl, a lower alkynyl, a carbonyl(e.g., an ester, a carboxylate, or a formate), a thiocarbonyl (e.g., athiolester, a thiolcarboxylate, or a thiolformate), an aldehyde, anamino, an acylamino, an amido, an amidino, a cyano, a nitro, an azido, asulfonyl, a sulfoxido, a sulfate, a sulfonate, a sulfamoyl, asulfonamido, a phosphoryl, a phosphonate, a phosphinate, —(CH₂)_(m)—R₈,—(CH₂)_(m)—OH, —(CH₂)_(m)—O-lower alkyl, —(CH₂)_(m)—O-lower alkenyl,—(CH₂)_(m)—O—(CH₂)_(n)—R₈, —(CH₂)_(m)—SH, —(CH₂)_(m)—S-lower alkyl,—(CH₂)_(m)—S-lower alkenyl, —(CH₂)_(m)—S—(CH₂)_(n)—R₈, or protectinggroups of the above or a solid or polymeric support; R₈ represents asubstituted or unsubstituted aryl, aralkyl, cycloalkyl, cycloalkenyl, orheterocycle; and n and m are independently for each occurrence zero oran integer in the range of 1 to 6. When the aryl moiety is phenyl, p isin the range of 0 to 5. For fused rings, where the number of potentialsubstitution sites on the aryl moiety is greater than five, the rangedefined for p must be adjusted appropriately.

Reaction Conditions

The methods of the present invention may be performed under a wide rangeof conditions, though it will be understood that the solvents andtemperature ranges recited herein are not limitative and only correspondto a preferred mode of the process of the invention.

In general, it will be desirable that reactions are run using mildconditions which will not adversely affect the reactants, the catalyst,or the product. For example, the reaction temperature influences thespeed of the reaction, as well as the stability of the reactants,products and catalyst.

In certain embodiments, the methods of the present invention areconducted at a temperature less than about 150 C. In certainembodiments, the methods of the present invention are conducted at atemperature less than about 140 C. In certain embodiments, the methodsof the present invention are conducted at a temperature less than about110 C.

In certain embodiments, the methods of the present invention areconducted at a temperature less than about 40 C. In certain embodiments,the methods of the present invention are conducted at ambienttemperature.

In general, the subject reactions are carried out in a liquid reactionmedium. The reactions may be run without addition of solvent.Alternatively, the reactions may be run in an inert solvent, preferablyone in which the reaction ingredients, including the catalyst, aresubstantially soluble. Suitable solvents include ethers such as diethylether, 1,2-dimethoxyethane, diglyme, t-butyl methyl ether,tetrahydrofuran and the like; halogenated solvents such as chloroform,dichloromethane, dichloroethane, chlorobenzene, and the like; aliphaticor aromatic hydrocarbon solvents such as benzene, xylene, toluene,hexane, pentane and the like; esters and ketones such as ethyl acetate,acetone, and 2-butanone; polar aprotic solvents such as acetonitrile,dimethylsulfoxide, dimethylformamide and the like; or combinations oftwo or more solvents.

The invention also contemplates reaction in a biphasic mixture ofsolvents, in an emulsion or suspension, or reaction in a lipid vesicleor bilayer. In certain embodiments, it may be preferred to perform thecatalyzed reactions in the solid phase with one of the reactantsanchored to a solid support.

In certain embodiments it is preferable to perform the reactions underan inert atmosphere of a gas such as nitrogen or argon.

The reaction processes of the present invention can be conducted incontinuous, semi-continuous or batch fashion and may involve a liquidrecycle operation as desired. The processes of this invention arepreferably conducted in batch fashion. Likewise, the manner or order ofaddition of the reaction ingredients, catalyst and solvent are also notgenerally critical to the success of the reaction, and may beaccomplished in any conventional fashion.

The reaction can be conducted in a single reaction zone or in aplurality of reaction zones, in series or in parallel or it may beconducted batchwise or continuously in an elongated tubular zone orseries of such zones. The materials of construction employed should beinert to the starting materials during the reaction and the fabricationof the equipment should be able to withstand the reaction temperaturesand pressures. Means to introduce and/or adjust the quantity of startingmaterials or ingredients introduced batchwise or continuously into thereaction zone during the course of the reaction can be convenientlyutilized in the processes especially to maintain the desired molar ratioof the starting materials. The reaction steps may be effected by theincremental addition of one of the starting materials to the other.Also, the reaction steps can be combined by the joint addition of thestarting materials to the metal catalyst. When complete conversion isnot desired or not obtainable, the starting materials can be separatedfrom the product and then recycled back into the reaction zone.

The processes may be conducted in either glass lined, stainless steel orsimilar type reaction equipment. The reaction zone may be fitted withone or more internal and/or external heat exchanger(s) in order tocontrol undue temperature fluctuations, or to prevent any possible“runaway” reaction temperatures.

Furthermore, one or more of the reactants or the catalyst can beimmobilized by attachment to or incorporation into a polymer or otherinsoluble matrix.

Subsequent Transformations

A product synthesized by a method of the present invention may be eitheran end-product or an intermediate in a synthesis scheme. In cases wherethe product synthesized by a method of the present invention is anintermediate, the product may be subjected to one or more additionaltransformations to yield the desired end-product. The set of additionaltransformations contemplated comprises isomerizations, hydrolyses,oxidations, reductions, additions, eliminations, olefinations,functional group interconversions, transition metal-mediated reactions,transition metal-catalyzed reactions, bond-forming reactions, cleavagereactions, fragmentation reactions, thermal reactions, photochemicalreactions, cycloadditions, sigmatropic rearrangements, electrocyclicreactions, chemoselective reactions, regioselective reactions,stereoselective reactions, diastereoselective reactions,enantioselective reactions, and kinetic resolutions. The inventionexpressly comprises use of a method of the present invention as astep—either initial, intermediate or final—in the synthesis of known ornew pharmaceuticals, e.g., antivirals, antibiotics, and analgesics.

Combinatorial Libraries

The subject methods of the present invention readily lend themselves tothe creation of combinatorial libraries of compounds for the screeningof pharmaceutical, agrochemical or other biological or medical activityor material-related qualities. A combinatorial library for the purposesof the present invention is a mixture of chemically related compoundswhich may be screened together for a desired property; said librariesmay be in solution or covalently linked to a solid support. Thepreparation of many related compounds in a single reaction greatlyreduces and simplifies the number of screening processes which need tobe carried out. Screening for the appropriate biological,pharmaceutical, agrochemical or physical property may be done byconventional methods.

Diversity in a library can be created at a variety of different levels.For instance, the substrate aryl groups used in a combinatorial approachcan be diverse in terms of the core aryl moiety, e.g., a variegation interms of the ring structure, and/or can be varied with respect to theother substituents.

A variety of techniques are available in the art for generatingcombinatorial libraries of small organic molecules. See, for example,Blondelle et al. (1995) Trends Anal. Chem. 14:83; the Affymax U.S. Pat.Nos. 5,359,115 and 5,362,899: the Ellman U.S. Pat. No. 5,288,514: theStill et al. PCT publication WO 94/08051; Chen et al. (1994) JACS116:2661: Kerr et al. (1993) JACS 115:252; PCT publications WO92/10092,WO93/09668 and WO91/07087; and the Lerner et al. PCT publicationWO93/20242). Accordingly, a variety of libraries on the order of about16 to 1,000,000 or more diversomers can be synthesized and screened fora particular activity or property.

In an exemplary embodiment, a library of substituted diversomers can besynthesized using the subject reactions adapted to the techniquesdescribed in the Still et al. PCT publication WO 94/08051, e.g., beinglinked to a polymer bead by a hydrolyzable or photolyzable group, e.g.,located at one of the positions of substrate. According to the Still etal. technique, the library is synthesized on a set of beads, each beadincluding a set of tags identifying the particular diversomer on thatbead. In one embodiment, which is particularly suitable for discoveringenzyme inhibitors, the beads can be dispersed on the surface of apermeable membrane, and the diversomers released from the beads by lysisof the bead linker. The diversomer from each bead will diffuse acrossthe membrane to an assay zone, where it will interact with an enzymeassay.
